hi cyborg.
sorry i am not familier with Mit ECU.
Does 5808 is 220hp type?
As far as i know, there are 200/220/240, 3 diff kind of ECU for VR4.
I have checked 200 ECU, it is complete diff from 220 ECU and don't have the chip i am looking for. As for 240hp ECU, I have yet to have any chances to see it so don't know whether it has the chip.
Do u have any photo of your ECU's internal?
